Functional Features and Operator Benefits

The Siemens 6FM1495-1AB10 uses sealed membrane construction for industrial durability. You can wipe the surface clean without damaging internal electronics. The key layout includes numeric pad, cursor arrows, and programmable function keys. Furthermore, the keyboard provides audible feedback through built-in beeper on key press.

This peripheral requires no external power source beyond the HMI connection. The flat ribbon cable carries both power and signal lines efficiently. Additionally, the membrane surface resists dust, oil, and mild chemical splashes. You can mount the keyboard on a desktop or through a panel cutout.

Installation and Connection Guidelines

First, power down your WS 495 or OP panel completely. Next, locate the dedicated keyboard port on the rear or bottom side. Then, insert the ribbon cable connector into this port carefully. Finally, secure the cable using the strain relief clips on the panel.

You must avoid bending the ribbon cable at sharp angles. The Siemens 6FM1495-1AB10 does not include any mounting brackets or screws. Consequently, you need a compatible mounting frame or adhesive pads. Always test all keys after installation for proper actuation feel.

This operator keyboard works perfectly with legacy WS 495 stations. It also supports OP 25 and OP 35 panels for machine interfaces. You can replace a worn keyboard without replacing the entire HMI unit. The 1.5-meter cable allows flexible positioning away from the main panel.
